The 68-year-old grandfather of 12 who was killed yesterday by a Framingham police SWAT team in an early-morning drug raid was a retired MBTA worker described by shocked neighbors as the “nicest guy in the world.”

Eurie Stamps was not the target of the search warrant, according to the Middlesex District Attorney’s Office, and his death at the hands of police is under investigation.

Authorities said Stamps lived at the house with a woman whose son and another man were arrested in the raid on drug charges...

Police wouldn’t say whether the shooting was justified. No weapons were recovered from the home, prosecutors said, and the suspects do not face weapons charges.

After Stamps was shot, police called an ambulance and gave him first aid, authorities said.

Joseph Bush fan, 20, the son of Stamps’ com panion, Norma Bushfan, was arrested outside the house as police initiated the raid. Bushfan allegedly was carrying eight baggies of crack and $400 in cash. Devon Talbert, 20, was arrested in a rear bedroom.
